Independent lab testing and dose verification

By TJ McGovern · Updated August 18, 2026

Brewlune does not yet have independent finished-product test results, because no production batch has been manufactured yet — and this page will not pretend otherwise. What exists today is two kinds of documentation: formulation records, which support every mushroom-extract and magnesium dose on the bags (the extracts are 100% extract powders, so grams in equal milligrams on the label), and supplier specifications, which document the beta-glucan minimums and fruiting-body sourcing of the extracts themselves.

The caffeine figures are in a third, weaker class, and we print that plainly: they are derived estimates — coffee or matcha mass per serving multiplied by supplier-typical caffeine content — and instant-coffee caffeine varies roughly ±20% batch to batch. That is why every caffeine number on this site says "about."

The independent-testing program begins with the first production batch: every batch gets a finished-product assay panel from an independent laboratory, and the certificate of analysis ships as an attachment on that batch's ready email, with the batch number on your bag matching the COA. When the first report exists, it publishes on this page with the laboratory named — until then, no laboratory is named, because none has been engaged.

What supports each printed claim today?

One row per quantified claim, each naming its evidence class. No production batch has been manufactured yet, so the batch and test-date column reads the same for every row. It starts filling in with the first batch.

How verification works

What a COA is
A certificate of analysis is a laboratory report for one specific batch: what was measured, by what method, with what result. It is only meaningful when the batch number on the report matches the batch number on your bag — a COA without a batch match is marketing, not evidence.
Supplier COA vs. finished-product testing
A supplier COA covers an ingredient before we blend it — the extract supplier assaying its own lion's mane powder. Finished-product testing measures the blended product in the bag. Both matter and neither substitutes for the other: supplier documents establish what went in; the finished-product assay establishes what you actually drink.
Why extract doses are validated by records, not assays
No laboratory can measure "500mg of lion's mane extract" inside a finished blend — extract mass is not a molecule an instrument can find. What is measurable is the marker the extract carries: beta-glucans. So the extract doses are validated by formulation records (grams of 100% extract powder in equals milligrams on the label), and the assay verifies beta-glucan content against the supplier minimums.
What gets measured, and when
Caffeine, beta-glucans, heavy metals, mycotoxins, and pesticides — directly measurable in the finished product, assayed per batch starting with the first production batch. Magnesium is verified through the supplier's elemental fraction and the recorded input mass; theobromine joins the assay panel because cacao's natural content varies.
Cadence
Per batch, not per year. Each production batch gets its own panel, its own COA, and its own line on this page. The first email you get from us — the one that says your batch is ready — carries that batch's certificate as an attachment.

Reports

No finished-product reports exist yet — because no batch does. The first COA publishes here, with the laboratory named, the batch identified, and an HTML summary alongside the document so nothing is locked inside a PDF. Until then, the only documents that exist are the suppliers' own, linked below at their source — we don't re-host documents that aren't ours.

Questions people actually ask

+Is Brewlune independently lab tested?

Not yet — and we print that rather than imply otherwise. No production batch has been manufactured, so no finished-product testing has happened. The program is committed: every batch gets an independent assay panel covering caffeine, beta-glucans, heavy metals, mycotoxins, and pesticides, with the COA attached to that batch's ready email and published on this page.

+How does Brewlune verify the doses printed on its bags today?

Two ways, stated per claim. Mushroom-extract and magnesium doses are supported by formulation records: the extracts are 100% extract powders, so grams of input equal label milligrams directly. Beta-glucan minimums and fruiting-body sourcing are supplier-documented. Caffeine figures are derived estimates — printed as "about" — until the first finished-product assay measures them.

+Which laboratory tests Brewlune products?

None yet, so none is named — naming a laboratory before engaging one would be exactly the kind of implied verification this page exists to reject. The lab is selected when the first production batch is commissioned, and the certificate of analysis attached to your batch-ready email names it, along with the methods used.

+Can I see Brewlune's certificates of analysis?

Not yet, because none exist — a COA is a report on a specific batch, and there is no batch. From launch, each batch's COA ships as an attachment on that batch's ready email and publishes on this page with an HTML summary, so the results aren't locked inside a PDF. The batch number on your bag matches the report.

+What is the difference between a supplier COA and finished-product testing?

A supplier COA documents an ingredient before blending — the extract producer assaying its own powder. Finished-product testing measures the blended product in the bag you receive. Supplier documents establish what went in; the finished-product assay establishes what you drink. Brewlune's program uses both and never presents one as the other.

+How is the caffeine measured?

Today it isn't — it's calculated, and we say so. Each figure is coffee or matcha mass per serving multiplied by supplier-typical caffeine content per gram, and instant-coffee caffeine varies roughly ±20% batch to batch. That's why every caffeine number on this site says "about." From the first batch, caffeine is measured directly in the finished-product assay.

+Are Brewlune's mushrooms fruiting-body extracts?

Yes, in every blend, and this one is supplier-documented today: the extracts are Real Mushrooms products, produced by Nammex, stated by the supplier as fruiting-body-only with no mycelium-on-grain, with published beta-glucan minimums per species. The suppliers, origins, and certifications for every component are on the sourcing page.

Every supplier behind these components is named, with origins and certifications, on the sourcing page. Per-blend doses live on the dosage comparison page.
